2 Claims.

n This invention relates to certain new and useful improvements inwindow construction and particularly to the sash arrangement thereof.

One of its objects is to provide a window frame and sash constructionwhich is sini le, compact and inexpensive, and which embodies onemovable sash designed and arranged to afford the advantages of thecustomary two-sash window conu struction.

Another object of the invention is the provision of a windowconstruction which has been primarily designed for moderate pricedhomes, and which is constructed and arranged to pern mit the completeopening of the move. le sash above the window fra-ine and within theroom in which it is located.

A further object is to provide a window sash which can be easily removedfrom the frame when desired without disturbing any oi the customaryfacing or trim elements thereof.

In the accompanying drawingz-Figure 1 is an inside elevation, partly insection, oi a window frame and sash construction embodying my invention.Figure 2 is a vertical transverse section thereof taken on line 2-2,Figure 1. Figure 3 is a horizontal section taken on line 3-3, Figure 1.Figure 4 is a fragmentary View, similar to Figure 3, showing the mannerof effecting the removal of the sash.

Similar characters of reference indicate cor'- responding partsthroughout the several views.

VReferring now to the drawing, the window frame preferably consists ofupright sides or jam pieces 10 connected at their upper ends by a toppiece or lintel 1l and at their lower ends by a sill 12. may be providedwith the usual iinishing or trim strips 13 and 14, respectively. Asshown in Figures 2 and 3, this frame is so disposed relatively to thewall 15 within which it is mounted that it projects somewhat into theroom in which it is mounted, and as seen in those iigures, the lintel 11and sill 12 of the frame project inwardly beyond the plane of said Wall.

Applied to the window frame is a sliding lower Sash 16 and an upperfixed or stationary sash 17,

the lower sash being preferably of a greater height than the upper oneand Vin practice is such that, when the movable sash is raised,sufficient head room is afforded between the top of the frame and theceiling to accommodate it in its fully raised position and to provide awindow-opening of approximately the height of an average person. Thelower sash 16 is disposed Within the inwardly-projecting portion of theYare disposed inthe plane of the lower sash and The inner and outerfaces of this frame (Cl. Ztl-52.1)

window frame and is guided at its side edges in suitable upright ways orgrooves 18 formed in the jamb pieces 10 of the frame and located in aplane disposed inwardly of the room wall 15. These grooves extendthrough the top of the frame and the lintel 11 terminates at its inneredge at the outermost edge of the grooves inthe manner shown in Figure2, whereby the lower sash 16 can be opened the full length of the guidegrooves and in the open position overlie the adjoining wall of the room,as seen by dotted lines in Figure 2. These guide grooves for Vthe lowersash are preferably formed by a division strip 19 applied to the sidepieces of the frame between the contiguous faces of the upper and lowersash,

inwardly of the room wall 15, a suitable compartment 22 being providedfor housing them. By this arrangement, should the customary cordconnecting the sash with the weight become broken, the sash-weight willmerely drop to the bottom or the compartment 22 or on to the sill 12which is readily accessible by merely removing the upright insidefinishing strip 13 which constitutes the inside wall of suchcompartment.

For the purpose of facilitating the removal of A9() the lower sash 16when desired, I provide the bottoms of the guide grooves 18 withdetachable longitudinal strips 23 against the faces of which theopposing side edges of the window normally ride. Adjacent their lowerends, these strips are provided with suitable finger-engaging holes 24for conveniently effecting their removal. By this construction, when itis desired to remove the sash from the frame, the same is raised to a Ysuitable height sufficient to enable one to grasp ".100 the finger holes24' of the strips 23, whereupon the latter are removed by a combinedspringing and downwardly pulling action. With the strips l thus removed,the sash can be shifted bodily to one side or the other of the frameopening and in this position the opposite edge or" the sash will clearthe adjoining edge of the upright trim strip 13, as seen by full linesin LFigure 4, and enable the sash to be Ypulled inwardly and completely1.10

removed from the frame in the manner shown by dotted lines in saidfigure.

I claim as my invention:- 1. In a Window construction, a frame adapted:i for installation in a building-Wall and having its jamb pieces, silland lintel projecting inwardly from said Wall, the jalnb pieces havingupright guide grooves therein opening through said lintel and disposedin a plane inwardly of Jthe building- Wall, and a sash engaging saidguide grooves and projeotable above said frame in overlying relation tothe 10oxnWall,
